The equilibrium constant of the following isomerisation reaction at 400 K and 298 K are 2 .07 and 3 .42 respectively. Which of the following is/are correct? I. The reaction is exothermic II. The reaction is endothermic III. At 400 K 50% of cis-butene and 50% of trans-butene are present of equilibrium IV. Both at 298 K and 400 K , k 1 = k – 1
Options
- AI and IV
- BII and IV
- CI and III
- DI only
Correct answer
D. I only
Step-by-step solution
As on increasing temperature K e q is increasing so reaction is exothermic.
